use binomial formula
n = number of trials
p = probability of success
x = number of successes
P(x successes in n trials with probability p) = C(n,x)*p^x*(1-p)^(n-x), where C(n,x) = number of combinations of n items taken x at a time
here p = 0.304, n = 8.
Determine probabilities for x = 6, 7 and 8 and sum probabilities to get the final answer.
